To all whom 'it may @021.06m

Be it lmownthat I, Go'rrLrn L. E. KLING- nnln, e Citizen of the UnitedStatearesdng et Ornaheyin the bounty oilffDouglas and State of Nebraska,have invented certain new .and useful Improvements .in .SpringSpreaders, of "which 'the lfollevyingi s fa Specification.This.nventonrelatesto a ,spring spreader and i't has for its'oloject toprovidean improved deveeot this 'eharaetefr by `ineens of ivhiehtheleeves of eutonioible and other vehiele springe neey be readilyseparated lor the purpose ot'y permitting the insertion of `lubrieen'ttherebetween.'

Much et theA So .eelled hard riding of automobiles and many of thesqueaks may `be attributed to improper lubrieation ,of the eprlngs.

The device of the said inventionis siinilar to that Shown in rnyeo-pending application Serial No. 699,7 5 6, iledon the 17th dt-y `ofMareh, 19.24F, in that iteomprises tvvo elements movable toward and fromeaeh other under theiniiuence of screws said elements carrying banks ofwedges adaptedto ,enter between and separate the 'leaves of the springs-`The presentinvention relates to an irnproved mannerof mounting theWedges and to aniinproved form of Wedge, each lvfvedge having amultiplicity of points, so that when one point becomes dulled the Wedgemay be turned and another point brought to position to do thevvork. Y

Further objects and advantages of lthe invention will `be Vset forth inthe detailed description which follows: In the accompanying drawings:

The shape of'these Wedges Yis clearly'illuatrated in Fig. 3where ityvillbe seen that they are substantially .square at theircentral portions and have wedge points 1,0 upon each side. ThusWhenfonepointlbecoine's Worn from use the Wedge may flee."y

VThisfis accomplished by removing the set Ascrevvs 111andlifting the Wedge-bars out of the blocks 5 and Gatter the"bloclrshave'been'disengaged `from the operatingscrews 13 'and`14. It is to beunderstood that the screws lBand 14 do not turn, but upon the contrary7block 6 is engaged with the headed ends of these screws indicated atl?)aand 14@ and that the block 5 may be moved by nuts yvhich engagethe'threadsv of the `screws 13 and 1,4

said nuts constituting the hubs 15 and'lfof gear Wheels 17 and'l8.

The gear Wheels 17 and'lS are actuated by intermediate gear Wheel19 towhich rotation may be imparted through the mediurnyof a suitabletool,not shown, adapted to he 'engaged vv'ith an angular' end '20,constituting the shaft of gear 19. 'The gears17 1,8 andV 19 Varesupported kbetween spaced rplates 21 and 22. k'Flieseplates.are spaced.rorn eachother and are tied together'by' posts 23.

It is to be understood that any number or'` gears maybe employed andanyratioo,

gearing may be employed,` it lbeing ronly .end of block 5,.

The sereiv .le passes through bar fiend bleek 6` end ts head1/ia is oountersunk. inthe outerace of the bleek 6. This serevv oonlstitutes apivot upon which the block 6 may be bodily swung. dThe other ,end OiSaid disengaged -from screvvf" `13,

Vnecessary V in order to carry out the inven tion, to provide oneoperating gear Whichin head 13L of the screw 13,

plate is provided with ribs 60a upon its inner face over which theleavesA of the springs slide during theseparating operation. The opening60b is the opening through which .the screw 14 4will pass and theslotted portions 60c and'60d correspond to the slotted portions 6El and6b of Fig. 7 and serve the purpose described with respect to thoseportions.

p This tool is primarily intended for use in garages where it will have.to be capable of operating `upon. springs havingy leaves of varyingthickness. In other words the leaves of the springs of one automobilemay vary-materially in thickness from those of another automobile.l Thusit is very desirable to provide afstructure of such nature thatthekwedges may be readily varied in thickness by the substitution of aVthicker or thinner set of wedges Yas the occasion may require. Thestructure herein shown and defs'er-ibed admirably Vadapts itself to thispurpose since, by the removal of the set screws 11, thebars may bewholly removed from the lblock and the wedges rapidly strung thereon.Furthermore it is not essential that Vthe screws 13 and 14 pass throughthe wedge carrying bars, since these bars may lie wholly inwardly of thescrews as illustrated in the modified form in Fig. 9, `wherein 70 is theblock, 71 is the .wedge'carrying bar and 72 indicates a wedge'thereon.The outer end of the bar engagesslotted portions 70a of block 7 0 and isheld in place by av set screw 73. However it will be noted that thescrew 14 .lies outwardly of bar 71 and thus, by y `merely removing saidscrew 73 the bar with kits bank of wedges may be slipped'out ofengagement with the block. Thus one set of wedges may be removedandanother set.

substituted, without disengaging the block from the loperating screws.For preventing the screws 13 and'14 from turning I provide Yribs* 5Xy onblock 5 which engage in grooves 5z of said screws@ It is to beunderstood that the invention is not limited to the preciselconstructionset forth but that it includes within its .purview whateverchanges fairlycome within either vthe .terms or the `spirit oftheappended claims. Y I y Having described my invention what I claim is:

1; A device of the character described 6b in which this ymounted thereonand ing.

vwedge bars carried thereby, 'wedges upon ysaid bars, screws passingthrough said blocks and means engaged with comprising a wedge supportingblock, a wedge bar angular in cross'section removably engaged with theblock and a bank of .wedges strungV upon said bar and held v againstturning with respect thereto by their configuration.

2. Astructure as recited in claim l wherein said wedgesdcomprise amultiplicity of operating points adapted to be successively brought intooperation by being turned to a new position upon .the bar. l Y

3. In adevice of the character described the combination with asupporting element, of a plurality of wedges non-rotativelv supportedthereby, each of said lwedges having al multiplicity of operating pointsadapted toy be successively brought into operation by being turned to anew position with respect to said supportingvelement.-

4. A device of the character described comprising a pair of elements apair of screws on which said elements are supported, means engaged withthe screws for forcing said elements toward each other, one of saidelements` carrying a wedge carrying bar which is angular in crosssection and a plurality of wedges strung upon said bar and held by itsangular shape from turning with respect thereto.

5. A structure as recited Yin claim 4 wherein saidV bar is removablyengaged with said element and wherein said wedges are each provided witha multiplicity of points `adapted to be successively brought intoopbeing turned with respect to said comprising Va supporting block,notchedV out at its vopposite ends, a bar seated in said notched'outport-ions and held in position there-in by set screws and a plurality ofwedges strung upon said bar, said bar and wedges being provided withinterengaging means for holding the wedges against turn- V7. Aldevice ofthe character described comprising a pair of wedge blocks, a pair ofwedge bars angular in cross section carried thereby, a bank of multiplepointed wedges upon said bars, screws passing through said blocks andmeans engaged with said screws and operating upon each of said screwssimultaneously, for moving the blocks kforcibly toward each other.

8. A device of thecharacter described comprising a pair of wedge blocks,a pair of a bank of said screws and operating upon each of said screwssimultaneously for moving' the blocks forciblytoward each other, saidVwedges being movable y to varying positions around said bars and in suchvarying positions preioo senting diierent points of contact to the work.

9. A structure as recited in claim 8, in combination with means forholding the screws against tui-ning with respect to one of said wedgeblocks while permitting said wedge block to move longitudinally of saidscrews.

10. In a device of the character described, the combination with a blockand means for imparting bodily movement to said block, a wedge barmounted upon said block for bodily removal therefrom and a plurality ofwedges strung vupon said bar, each of said wedges having a plurality olfpoints which may be successively brought into operation by turning thewedges to new positions with respect to the said bar, said bar andwedges being provided with interengaging means for holding the wedgesagainst turning.

,ln testimony whereof lie aflixes his signature in the presence of twowitnesses.
